8GB 980m OC on AW 17 R3 - 200mhz maximum?

Hi there,

I've been having a go at overclocking my new AW laptop but I don't seem to be getting the same results as everyone else. I was wondering if anyone would be able to shed a light on why this is.

Spec:
Alienware 17 R3 UHD
8GB 980m
6820hk CPU OC'd to 4.3 (4.1 daily)
16GB DDR OC'd to 2666

Nvidia Inspector OC settings:
Base +225MHz
Memory +200MHz
Voltage offset 0

The above runs brilliantly and I'm scoring 13671 on 3DMarks11.

What's throwing me is that I can't really increase the base or the memory clock without running into glitching and crashing. I tried upping the voltage incrementally but it's made next to no difference to the system stability. I've read on here of people running 400+MHz on the memory but I can't even get close to that.

Any help or insight would be greatly appreciated.

Thanks

Scott

 

Incidentally, I re-ran the bench and hit 13601 with the CPU set at 4.1 so overclocking it to 4.3 only made a marginal difference.

 

Memory voltage cannot be increased without a hardware mod.. You are increasing core voltage.. so if +200 is your best, you are stuck on that!

 

Ahh that would explain it then. Do you think I'm better dropping the memory further and increasing the clock.... or will it not make a difference?

Thanks

 

Nahh, if the memory OC is stable, leave it there.. Be careful Ocing 24/7... It does put extra stress on the GPU and with your BGA Machine, it's pot luck if anything fails and needs replacing..

 

and why you don't get BGA to begin with!

 

It was the best I could afford unfortunately. I could have gone with the MSI but the same spec was over 2k and I was really stretching my budget to get the best bang for buck.

Fortunately I was just playing around with the OC. I'm not a hardcore gamer, I just wanted to see what she would do. My daily OC on the CPU is back down to 4.1 with stock voltage.

I've pulled the ram back also as there wasn't much of a performance gain. GPU will be back to stock clock etc unless I feel o need it, which will be a while I imagine.

Thanks for the help.

 

200Mhz is amazing if that's from 1126Mhz. That's a 1326Mhz core clock, which surpasses just about all 24/7 980M SLI clocks.

 

Really? I didn't think that was anything special. Unless I'm missing something from other peoples results.

There's a thread on here regarding OCing the 980m and a lot of people were managing 135 (stock limit?) and 400/500mhz on the memory. Digging around found that people with unlocked bios were getting 225-250mhz on the clock and 350mhz on the RAM.

 

250mhz core puts it nearly at 1.4ghz. It takes dual adapters with SLI so owners need dual PSU to run that. I would be very happy with a 200 OC.

 

Don't know where your located but for the price you paid for this, you could get a Clevo/Sager P750/770DM laptop with a desktop CPU + MXM GPU..
